Detailed ways

overall basic technology

In a first example, a fluorometer generally designated 20 according to the invention can be configured to measure peak T-tryptophan-like (λ _ex/em = 280/340nm) and peak A-humic/fulvic acid-like ( λ _ex/em = 280/450nm), eg using single excitation source/dual emission detection as a general means of identifying water affected by sewage. Positive identification of water affected by sewage is complicated because sewage can be more accurately determined by the near simultaneous identification of multiple fluorescent species. For the particular case at hand, and according to some embodiments of the present invention, it is possible to manage to identify two substances, requiring two detected fluorescence emission wavelengths, near simultaneously within a single sensing volume. Combinatorial information from multiple fluorophores is used to address the single problem of wastewater identification. The present inventors have recognized that a single emission wavelength alone cannot definitively determine the presence of wastewater, and provide the new and unique techniques disclosed herein to address this "single emission wavelength" problem in the art.

Furthermore, the spirit of the invention is not intended to be limited to the identification of only two fluorophores, but is intended to cover the possibility of near-simultaneous detection of multiple fluorophores, eg comprising three or more fluorophores. According to some embodiments, this concept can be extended to include multiple excitation sources and multiple emission wavelength detection for near-simultaneous detection of multiple fluorescent species within a single sensing volume. For water quality monitoring, the presence of polyfluorophores tends to obscure or interfere with any specific desired analyte.
